About _NPCScan

If you care at all about my wishes, you won't download this AddOn from SolidIce: They are leeching it from the site I actually choose to put it on.

_NPCScan helps you find rare mobs through the use of dynamic target macros, mouse over alerts and for Vignette mobs proximity. Once a mob is found by one of these methods an on screen alert is displayed, in addition to an audio alert.

_NPCScan & Warlords

Due to changes in how the game caches mobs in WoD, it is looking like _NPCScan will no longer be able to auto detect non-Vignette mobs. Due to this the only way to find pre-MoP rares via _NPCScan will be via mouse over or the new dynamic target macro keybind being added. The new keybind will trigger a /targetexact …” macro that updates with tracked mobs based on the zone you are currently in. Vignette mobs will still automatically trigger an alert when the mob gets in range, and should work more reliably due to updates to the Vignette API.

V6.x Changes
  • Cache Scanning Removed - Due to changes in the way WoW cache mobs, NPCScan can no longer auto alert when mobs are nearby like it use to.
  • Dynamic TargetExact Macro Keybind - NPCScan now has a keybind you can set that will try to /exacttarget tracked mobs. This macro will dynamically update based on the zone you are in and which mobs are being tracked.
  • Updated Vignette Alerts - Vignette Alerts are now more reliable and show the actual mob when detected the majority of time.

If you have a question check the FAQ, or a problem create a ticket

If you have a question/comment about _NPCScan.Overlay please post it in it's comment section.


Dynamic Target Keybind

NPCScan now includes a keybinding that will trigger a stored dynamic target macro. Each time it is pressed, the keybind will trigger a /targetexact <mob name> for every tracked mobs in the current zone you are in, in addition to any custom added mobs. This macro will be auto updated based on the zone you are currently in. To access this feature, just set a keybind under the Keybind->Other_>NPCScan section. Note: To search via the keybind, you will need to continuously push the bind. Pushing it once will only trigger it once, it does not auto scan like it did Pre WoD.


NPCScan now tracks "vignettes". These are the little skulls appear on the minimap, that denote rare mobs. This is a beta feature and is disabled by default. Enabling this feature will alert you to a rare that's within minimap range, without any worries about having to clear your cache. When you get an alert you will be shown a target button similar to the standard mob alert, letting you know that a vignette mob was detected. Clicking on the target button will try and target the mob.

“Found” Alert

When a rare mob is found, _NPCScan alerts you by playing a loud and distinctive sound, making your screen pulse red, and displaying an animated Targeting Button. To get a feel for what this alert looks and sounds like, try the “Test Found Alert” button in the addon's main Interface Options panel. (See the Options section below.)

Targeting Button

When clicked, the targeting button tries to target the most-recently-found mob.&nbsp; You can also bind a key to hit this button. If the default button position isn't to your liking, you can move it while holding your CTRL key.

Note: The button cannot be shown during combat. In the unlikely case that you do find a rare while fighting, the button will appear after you leave combat. You will still hear the alert however, and the name of the mob will appear in your chat log.


_NPCScan's main options window can be accessed from the Interface Options menu. This panel includes a “Test Found Alert” button, various ways to customize the alert sound, and an option to suppress cache warning messages on log-in. New sounds can be added to the alert sound dropdown menu by installing SharedMedia-type addons.

Search List

The list of mobs that _NPCScan searches for can be modified easily through the Interface Options panel, however it comes pre-configured with most rare mobs.; To access the mob list, type “/npcscan”. Grayed out NPCs in a list aren't being searched for, either because they're cached or not needed for their achievement.

The first tab available lists Custom NPCs that you can enter or remove manually. NPCs that are already cached show a red “X” in the first column. You can add or remove Custom NPCs with the [+] and [-] buttons at the bottom right.

All other tabs control achievements like Bloody Rareand Frostbitten. These tabs show an additional column on the right with green check marks for completed achievement mobs. You may enable or disable tracking each achievement with its tab's checkbox.

To remove non custom mobs from a tab, click on the mob that you want to remove and then click on the "Remove" button. This will remove the selected mob from the current tab and add it to the Ignore List Tab. If you ever want to restore a Ignored Mob, select it from the "Ignore List" tab, click the "Remove" button and it should be added back to its original tab.

The “Search for completed Achievement NPCs” checkbox at the top left of the pane allows you to keep looking for mobs you no longer need for achievements.

Finding NPC IDs

A mob's NPC ID is its unique identification number, and it can be found on sites like WowHead or WowDB For example, search for the mob “Dirkee” on WowHead and go to the mob's page.&nbsp; That page's URL will look like

32500 is Dirkee's NPC ID.

    The tamable mobs would get cached whether I set a tooltip for them or not though, so I figured it'd be more useful to always show when false alarms occur. Otherwise, some people might try leaving Dalaran to hunt a rare without even knowing that it got cached. What I should have said is there's no way to avoid tamable mobs polluting the cache.

    As for scanning NPC IDs by zone, I decided against it simply because the current CPU load is so small and I'd need to rewrite quite a bit to get that working. I might have to change my mind when Cataclysm rolls out though...
  • #428
    *nods* Good point - the cache is the crux of the problem. I too have found it highly annoying that there is no way to 'see' a mob multiple times due to the way the cache works.

    Even more frustrating is that there is no way to check the validity of an entity (real mob or tamed pet) unless we manually target it and do a bitwise check of its GUID, and Blizzard removed the ability to auto-target long ago, making the possibility of true 'area scanning' impossible.
  • #418
    Does the alarm sound when you're tabbed out?

    I tried testing then tabbing out but that cut the sound...
  • #419
    Check the default UI's sound options menu for a checkbox labeled "Sound in background" or something similar. That will let sounds play even when the game's in the background.

    There is one catch though: Since 3.3 if you play in fullscreen mode, _NPCScan won't work while the game is in the background. The only way around this is to play the game in Windowed Mode (in video options). Thankfully you can set WoW to play in /Maximized/ windowed mode, which looks nearly the same as Fullscreen and still works.

    Is there a way to add overlays manually? Added a bunch of vanilla rares but would love to have them show up on the map, even if it was only the World map. Wowhead lists general spawn areas, if it's possible I'd love to try it. Thank you for an amazing addon :D
  • #412
    Just wanted to say thank you for creating this addon. I downloaded it a couple hours ago to try and find Arcturis and decided to check SB before logging off. While flying into Rivers Heart it tracked Aotona. Flew over to the area and tamed him. Thanks again, my first rare pet. :)
  • #410
    I LOVE this addon, but is there a way to easily add in rares fro the old world, and not have to put them in one at a time?
  • #408
    Thanks for the help.
    The NPC is now on the list without a X but it havent written any location.

    like this Skoll --- 35345 (ID) --- Storm Peaks

    It also isnt shown in the litle box when i look at grizzly hills on my world map.

    Does this mean that i wont be told when it appears and if yes how do i fix it?
  • #409
    _NPCScan will still find it in Grizzly Hills. It has no map though, since I don't know where he patrols yet.
  • #406
    Just noticed something:

    When i look on the map for Grizzly Hills the name is not in the box...

    Can u help me to get him there?

    IF it helps ive downloaded the addon from WowMatrix today at about 22.00 (says its fully updated)

    If havent noticed its me who wrote the reply under this too (couldnt edit my post)
  • #405
    Hi first i wanna say thx so much for making this addon xD

    Ive just installed the newest version of the addon so i can get the new spirit beast arcturis.

    The npc is on the list but the text i gray and theres a {cross} before the text.

    Ive tried clearing the list and put in it myself but nothing changed.

    Can u tell me if that means NPCscan is unable to show when he spawns?
  • #407
    The red "X" means that you've already seen Arcturis (or a tamed pet version of him), so you'll need to clear your cache. See the section in the description titled "Clearing Your Cache" for detailed instructions.
  • #401
    Hey everyone. Has anyone else had any trouble getting the alert to sound? I've messed with every adjustment I can find for sound, and have not been able to get the alert to scream at me. The test succeeds, just no sound.

    Thanks for any ideas!!
  • #403
    Ok, there was one thing I didn't try before. I have two sound file options, "Xylo" and "Default". Mine was on Xylo. I switched to default and have sound now on the test.
